AEM Wideband Sensor

[jackyft]

Dear All,

I have another question about Wideband Sensor.

I was installed AEM wideband Lambda to replace the stock o2 sensor. I connected "white" cable of wideband to D10 (ELD). Disabled ELD. But I found the meter has reading normally. But smanager only show voltage between 2.7x to 2.8x V. Attached w/ the calibation and log for your reference.

Do I need to cut the D10 cable rather than "T" the cable? Or do I need to cut some resistance inside the ECU? I bought from HA Sports including a P28 ECU.

Thanks in advance.

Yes the wire must be cut and not T'd. You must also cut the resistors mentioned in the help file.

Oh it's clear. How about if I ust D14? Since the stock O2 was replaced. is it need to cut anything?

Thanks.

I connected to D14, it have normal reading.

I have another question, it's about knocking sensor. I have a b16a engine. Assume that will have knocking sensor. But when I try to enable knocking sensor. Error code knocking sensor on. Is there any trick for this?

Thx in advance.

I would recommend against using D14 as it cannot read the full voltage range. D10 would be a better input.

What ECU are you using?

I'm using P28 ECU bought from HA Sport. Do i just cut off the resister? or need to connect it by a jumper wire? Thx.

For Knocking Sensor, I just think about, mind is JDM ECU and JDM B16A, the ECU is P30, it including a logic board of Knocking Sensor. Is it will malfunction if I connect a P28 ECU on it? thx.

[Spunkster]

The P28 cannot use a knock sensor as it does not have the circuitry for it. You must disable it.

Thx for your information.

For cutting R136 and R138, is just cut it off? No need to solder?

[Spunkster]

You only need to cut one leg of each.

Oh. Thx for your kindly help!!!
